ALCOHOLIC-LEQLHD PU RIFIER.

S?ECIFICATION forming part of Letters Patent No. 710,669, dated October7, 1902.

Application filed April 4, 1902. Serial No. 101,308. (No model.)

To all whom it may concern.-

Be it known thatI, CHAUNCEY O. CLARK, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inAlcoholic- Liquid Purifiers, of which the following is a specification.

Myinvention relates to purifier mechanism for the treatment of alcoholicliquors for the purpose of removing therefrom all of the impurities andforeign substances carried in the liquid or held in suspension thereinby electrolysis as the liquid enters the treatingreceptacle after thefirst process of distillation, the withdrawal of the liquid from belowits upper surface, where floating impurities arise, its after removal toa compartment preferably filled with charcoal for its filtration, andthe separation of impurities of equal specific gravity with the liquidand which have not heretofore been removed by electrolysis or fioatage,and means for introducing and withdrawing the liquid, the decomposedresidue, the fioatage, and the washing of the filter and its contents.The action of the apparatus is continuous during the supply of liquidand is automatic, as the electric current will flow in sufficient volumeto attack the volume of impurities as presented, be the same more orless, according to the purity of the inflowing liquid. It has been foundthat by using this mechanism only one distillation of the liquid isnecessary, thus effecting the saving of the cost of the seconddistillation and the time employed for that purpose. It has also beenfound that a perfectly pure liquor is produced by this mechanism andthat it is no longer necessary to consume the long interval of timebefore the liquor is aged, which will be of great profit to the brewersof alcoholic liquors. Distillation does not wholly purify, as is provenby the fact that after distillation liquors must be set away todecompose and purify by time, which time is saved by the employment ofmy mechanism.

My mechanism is illustrated in the accompanying drawings, in whichFigure 1 is in general a central section with some of the parts inelevation. Fig. 2 is'an end elevation at the filter end.

Similar parts are indicated by similar reference characters throughoutthe views.

I employ a receptacle 1, which maybe made of oak when a cheapconstruction is desired; but when a more durable structure isrequiredthe cylinder 1 willpreferably be of copper, as shownin the drawings.Near the left end of the receptacle 1 and through its top aninlet-chamber 2 is inserted. It has a flange 3, which supports it onreceptacle 1, and above it a cover 4 is secured to the flange. The coveris provided with a neck 5, to which is secured an'inletfi, having aninlet-pipe 7 for conveying the inflowing liquid. Above 6 any suitablesafety appliance may be secured for the purpose of preventing excessivehydrostatic pressure within the receptacle. The cover is also providedwith insulated stuffingboxes 8 9, which permit the electrical conductors1O 11 to pass within the cylinder 2, while at the same time they preventany liquid from passing out. The stuffing-boxes are of the constructionfully set forth in my application for liquid-purifier filed January 22,1901, Serial No. 44,274. Within inlet-chamber 2 is an insulated lining12. Conductors 1O 11 are connected to a dynamo or source of electricalenergy exterior to the receptacle, and within chamber 2 they suspend aseries of perforated disk electrodes, 13 being anodes, and 14 beingcathodes, and their construction and suspension are fully set forth inmy former application, as above referred to. The inletchamber 2 has anopen lower end, through which the liquid passes into receptacle 1 afterits electrolysis, at which time the products of decomposition, which areof greater specific gravity than the liquid, will descend to the bottomof the receptacle 1, and at convenient times the deposit can be drawnout of the receptacle by means of a series of pipes 15, controlled byvalves 16 in connection with pipe 17, common to all. Toward the oppositeend of the receptacle from chamber 2 and mounted above the receptacle isa dome 18, within which arise the floating impurities above the level ofthe body of liquid, which completely fills the receptacle 1. Insertedthrough the top of the dome and entering the body of the liquid inreceptacle 1 is an outletpipe 19. Beyond dome 18 the receptacle 1 has apartition or bulkhead 20, which with head 21 forms thefiltering-compartment 22, with a screen 23 reaching across its upperpart, below which the compartment is filled with charcoal or othersuitable filtering material. From the top of dome 18 a deliverypipe 2%passes upward, then outward and downward, and enters the bottom ofcompartment 22, and the entering fluid under pressure percolates throughthe interstices between the particles of filtering material, where theimpurities are collected and retained, and the pure liquid passes abovescreen 23 and enters pipe 25 and is conveyed away ready for immediateuse. A valve 26 controls pipe 24. Dome 18 has a surface blowpipe 27,controlled by valve 28 for the removal of the floating impurities. Awash-out pipe 29 enters under compartment 22, and by its use thefiltering material is cleansed. A head 30 closes the end of thereceptacle opposite the filtering-compartment,and it is provided with amanhole 31 for gaining access to the interior of the receptacle.Filter-head 21 is likewise provided witha manhole 32,whereby filteringmaterial may be inserted and removed.

I claim- 1. In a liquid-purifier, a horizontal cylindrical receptacle,an insulated lined inletchamber inserted therein, a series of perforateddisk electrodes suspended in the chamber, electrical conductorstherefor, a dome located on the receptacle for the collection offloating impurities, a filtering-compartment within the receptacle andmeans for conveying liquid to the inlet-chamber for electrolysis, thenceto the receptacle, thence from a point below the top of the liquid inthe receptacle to the filter, and from the filter to a desired place ofdelivery.

2. In a liquid-purifier, a horizontal cylindrical receptacle havingmeans thereto atfor the electrolysis of entering liquid, a compartmentwithin the receptacle for filtration, filtering means in thecompartment, and means exterior to the receptacle to remove the liquidafter its electrolysis to the filtering-compartment for its passagethrough the filtering material.

4. In aliquid purifier and filter, a horizon tal cylindrical receptaclehaving a portion thereof for the storage of filtering material, achamber entering within the receptacle and for a series of perforateddisk electrodes therein, a raised portion above the receptacle andopened thereto for the collection of floating impurities, means towithdraw thefioating impurities, means entering the body of theelectrolyte thereafter passing through and out of the raised portion andentering the filtering portion of the receptacle, and whereby theelectrolyte shall pass through and be subjected to purification byfiltration, and means to withdraw the electrolyte from the filter.

5. In a liquid-purifier, a horizontal cylindrical receptacle having afiltration-com partment, a head for the receptacle and for the filter,manholes in the heads, a liquid-passage from the receptacle to thefilter; means to withdraw deposit from the receptacle at its lower side,means to wash out the filter, an inflowing-chamber for the receptacle, aseries of perforated disk electrodes within the inflowing-chamberconstructed to intercept the inflow and subject it to electrolyticaction, and electrical conductors for the electrodes.

6. In a liquid-purifier, a horizontal cylindrical receptacle having apart thereof for the electrolysis of in flowing liquids, and within thesaid part a series of intercepting disk electrodes with electricalconductors therefor; another part of the receptacle for holdingfiltering material, a liquid-passage from the electrolytic portion tothe filtration portion of the receptacle, a screen at the upper part ofthe filtration portion, and means to pass liquid within the receptaclefor its electrolysis, thence to the filter portion for its filtration,and for its Withdrawal from the filter, and above its screen, after itsfiltration. In testimony whereof I aifix my signature in presence of twowitnesses.
